Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe processing equipment, in particular to a directional punching device for stainless steel pipes. Background Art

[0002] Steel pipes are widely used in our daily life. They have a wide range of uses. During the use of steel pipes, it is often necessary to punch holes on the surface of the steel pipes to meet the processing and use of the steel pipes. There are many types of existing pipe punching machines. Some pipe punching machines can punch holes in the pipes individually, while some pipe punching machines can punch multiple holes on the outer surface of the pipe at the same time.

[0003] In existing pipe punching machines, a fixed drill bit is generally used to punch holes in a moving pipe. During the punching process, manual labor is required to push the pipe towards the fixed drill bit to punch the pipe. On the one hand, this requires a lot of manpower and has low work efficiency. On the other hand, the current punching machine is not easy to adjust, making it difficult to control the punching spacing. Moreover, when manually pushed, the pipe rotates axially, causing the punching position to shift, affecting the punching efficiency and pass rate. Utility Model Content

The implementation of the present invention is not limited to the following embodiments, and the present invention involves relevant necessary components in this technical field, which should be regarded as common knowledge in this technical field and can be known and mastered by technical personnel in this technical field.

[0026] like Figures 1 to 5 As shown, a directional punching device for stainless steel pipes includes a processing platform 1, a guide rail 101 is provided along the length direction of the processing platform 1, a first clamping device 2 is provided at one end of the guide rail 101, a second clamping device 3 is provided at the other end of the guide rail 101, and a punching device 5 is provided on the side of the processing platform 1 corresponding to the second clamping device 3;

[0027] A sliding platform 104 is provided on the guide rail 101, and a third clamping device 4 is provided on the end surface of the sliding platform 104. A first linear drive device 102 is provided at the bottom end of the first clamping device 2, and the sliding platform 104 is connected to the output end of the first linear drive device 102;

[0028] like Figure 1 As shown, in the technical solution of the processing platform 1 of the present invention, the first clamping device 2 is fixed to one end of the processing platform 1, and the second clamping device 3 is fixed to the other end of the processing platform 1. A guide rail 101 and a sliding platform 104 are provided between the end surface of the processing platform 1 corresponding to the first clamping device 2 and the second clamping device 3. The third clamping device 4 is fixed on the sliding platform 104 and slides horizontally along the length direction of the guide rail 101.

[0029] The clamping axes of the first clamping device 2, the second clamping device 3 and the third clamping device 4 are aligned. A first linear drive device 102 is provided at the bottom of the first clamping device 2 to drive the third clamping device 4 to move linearly toward the second clamping device 3. The third clamping device 4 clamps and fixes the steel pipe, and the first clamping device 2 and the second clamping device 3 clamp and restrict the circumferential swing of the steel pipe, but do not restrict the axial movement freedom of the steel pipe.

[0030] When the first linear drive device 102 drives the steel pipe to move axially to the corresponding position and pauses, the punching device 5 drills holes in the steel pipe from top to bottom. The first linear drive device 102 repeatedly drives the steel pipe to move axially and pauses, and the punching device 5 can continuously punch holes at equal intervals on the outer surface of the steel pipe.

[0031] like Figures 1 to 3 As shown, in the technical solution of the first clamping device 2 of the present invention, the first clamping device 2 includes a clamping base 201 arranged at the end of the guide rail 101, and a clamping disc 202 and a wheel disc 203 arranged in the clamping base 201. A first through hole 2021 is penetrated by the axial center position of the clamping disc 202, and a plurality of guide grooves 2022 are arranged around the first through hole 2021. A driving slider 2023 is arranged in the guide groove 2022. A clamping pulley 2024 is provided at one end of the driving slider 2023 facing the first through hole 2021, and a spring 2025 is provided at the other end of the driving slider 2023.

[0032] A plurality of arc-shaped grooves 2031 are provided in the thickness direction of the wheel disc 203 corresponding to the position of the driving slider 2023. The end face of the driving slider 2023 is provided with a transmission block 2026 extending into the arc-shaped groove 2031. The outer surface of the clamping base 201 is provided with a handle 2032 for driving the wheel disc 203 to rotate.

[0033] It should be noted that the first clamping device 2 is used to clamp the outer surface of the steel pipe to protect the steel pipe from vibration and swing during axial movement and drilling. Specifically, the steel pipe passes through the middle of the clamping base 201, and the driving slider 2023 on the clamping disk 202 clamps the steel pipe. The wheel 203 opens the driving slider 2023 on the clamping disk 202. When the steel pipe needs to be clamped, the handle 2032 is pushed to drive the wheel 203 to rotate, which is beneficial to the The arc-shaped slide groove 2031 on the wheel 203 drives the transmission block 2026 to move, so that the driving slider 2023 compresses the spring 2025 along the guide groove 2022. At this time, after the steel pipe passes through the first through hole 2021, the handle 2032 is pushed in the opposite direction, so that the driving slider 2023 is reset under the action of the spring 2025, and the clamping pulley 2024 at the end of the driving slider 2023 contacts the outer surface of the steel pipe and applies force to clamp it.

[0034] Furthermore, in the above scheme, a second through hole 2033 of the same size as the first through hole 2021 is penetrated along the axis of the wheel 203, and a third through hole 2011 is penetrated in the horizontal direction of the clamping base 201. The first through hole 2021, the second through hole 2033, and the third through hole 2011 are coaxially aligned, and the steel pipe is penetrated into the first through hole 2021, the second through hole 2033, and the third through hole 2011 in the clamping state.

[0035] like Figure 5 As shown, in the technical solution of the second clamping device 3 of the present invention, a clamping base 301 is provided at a position of the processing platform 1 corresponding to the second clamping device 3, and the second clamping device 3 includes a first clamping rod 302 provided in the clamping base 301, and a second clamping rod 303 and a third clamping rod 304 provided on both sides of the first clamping rod 302;

[0036] A second linear drive device 103 is provided under the processing platform 1. The output end of the second linear drive device 103 is vertically upward and connected to the bottom end of the first clamping rod 302. The first clamping rod 302, the second clamping rod 303 and the third clamping rod 304 are all provided with a first clamping wheel 305 at the top.

[0037] Furthermore, in the above embodiment, a movable chamber 3011 is provided in the clamping base 301, and a first notch 3012 is provided at the top end of the movable chamber 3011 corresponding to the position of the first clamping rod 302, a second notch 3013 is provided at the position of the second clamping rod 303, and a third notch 3014 is provided at the position of the third clamping rod 304;

[0038] The middle portion of the second clamping rod 303 is hinged to the inner wall of the second slot 3013 near the opening position, and the middle portion of the third clamping rod 304 is hinged to the inner wall of the third slot 3014 near the opening position.

[0039] Furthermore, in the above solution, the top end of the first clamping rod 302 extends outward along the first notch 3012 , and the first clamping rod 302 is provided with triangular protrusions 3021 protruding toward both sides in the corresponding movable chamber 3011 ;

[0040] Second clamping wheels 306 are provided at the bottom of the second clamping rod 303 and the third clamping rod 304 . The second clamping wheels 306 are in contact with the inclined edges on both sides of the triangular protrusion 3021 .

[0041] It should be noted that the second clamping device 3 clamps both sides of the steel pipe through the second clamping rod 303 and the third clamping rod 304, and supports the bottom of the steel pipe through the first clamping rod 302. When in use, the second clamping device 3 is in an open state. After the steel pipe is placed in the second clamping device 3, the second linear drive device 103 drives the first clamping rod 302 to move upward, and the second clamping rod 303 and the second clamping wheel 306 at the bottom of the third clamping rod 304 slide along the inclined edge of the triangular protrusion 3021 with the movement of the first clamping rod 302, so that the end of the second clamping rod 303 and the end of the third clamping rod 304 move toward each other, realizing the clamping effect from both sides of the steel pipe.

[0042] like Figure 4 As shown, in the technical solution of the third clamping device 4 of the present invention, the third clamping device 4 includes a locking base 401 and a locking ring 402 sleeved on the outer surface of the locking base 401, the locking base 401 is cylindrical, the outer surface of the locking base 401 is provided with an external thread 403, the inner surface of the locking ring 402 is provided with an internal thread 404, and the locking ring 402 is screwed and fixed to the outer surface of the locking base 401.

[0043] Furthermore, in the above scheme, the locking base 401 is provided with a fourth through hole 405 coaxially aligned with the first through hole 2021, and the locking base 401 is provided with a clamping block 406 at the end corresponding to the fourth through hole 405. The clamping block 406 is arranged at equal intervals around the outer edge of the fourth through hole 405 and is integrally formed with the locking base 401, and the locking ring 402 is provided with a conical through hole 407 at the position corresponding to the clamping block 406.

[0044] It should be noted that the third clamping mechanism is used to lock the steel pipe. After the steel pipe passes through the fourth through hole 405, a gap is formed between the outer surface of the steel pipe and the clamping block 406. By rotating the locking ring 402, the clamping block 406 is squeezed through the tapered through hole 407 on the locking ring 402, so that it fits and clamps the outer surface of the steel pipe, thereby limiting the axial movement of the steel pipe.

[0045] It should be noted that the first clamping device 2 and the second clamping device 3 limit the axial swing of the steel pipe, but do not limit the axial movement of the steel pipe, so that the first linear drive device 102 can drive the third clamping device 4 to clamp the steel pipe and move axially toward the punching device 5, thereby realizing equidistant drilling in the length direction of the steel pipe.

[0046] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
